HI all,
I bought this boat a year and a half ago and noticed this problem while performing the initial survey before purchase. The surveyor noted the problem and suggested it be fixed (among others), but otherwise considered the vessel "seaworthy". About six months ago, I redesigned and replaced the batteries and all components (bus bars, ground terminals, isolator, combiner, breakers, cables/wires, terminal ends, fuses, etc...) within the box, including the battery switch. the system (including an inverter) was engineered by Northern Arizona Wind and Sun and they also reviewed my install diagrams to confirm. Despite the success of the install, it did not seem to resolve the issue. I had been so excited about all my new goodies and the increased performance of the electrical system, that I called the project a success and sort of left that nagging little tidbit about the battery switch in the background.
Well, the honeymoon has faded and my concern is re-emerging. I am wondering if I have a ground fault from the distribution panel. All of this wiring is original (1987) or at least upgraded from previous owner. I have replaced a couple of DC circuits as well as the AC wiring (for a galvanic isolator and the inverter), but main positive and negative are original. My next step is to begin to troubleshoot this and see if I can isolate where the problem really is.
Does anyone out there know anything about this? I am very much amateur and consider all things electrical as black magic. I have recently mounted (2) 320 watt solar panels and I am itching to connect, but worry about the battery switch problem.
The boat is a 1987 Hunter Legend 37.
Inverter is Victron Multiplus 3000
Batteries are (3) 100 ah Battleborn Lithium Ion + (1) West Marine AGM starting battery
Not sure what else might be relevant to help understand the issue
Thanks!
